Abstract
A MIXTURE of three parts of ethylene dichloride and one part of carbon disulphide (by volume) applied at the rate of 0.6 c.c./litre of storage space by pouring the liquid on to the surface has been effective for some years in preventing insect damage to maize grain (var. Tsolo) stored in closed bins for subsequent sowing. In 1956 the variety Mexican Elite was grown instead of Tsolo, and the grain after storage was found to have a very low germination capacity. A series of experiments was carried out to test the hypothesis that the insecticide was affecting the grain adversely, and that some varieties of maize were more susceptible than others to this treatment.
